CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/129,413 filed on Mar. 6, 2015, entitled “DELIVERY OPTIMIZATION OF EMAIL MESSAGES,” the entirety of which is expressly incorporated herein by reference.

BACKGROUND

Currently there are a number of different formats for electronic communication for messaging including instant messaging, electronic mail (email) and text messaging, among other formats. Many of these formats have specific advantages and drawbacks to using them. For example, messages sent via email are known to have inherent latency issues. Other communication formats, such as instant messaging provide real time communication but do not provide other mechanisms for allowing more rich collaboration features.

It is with respect to these considerations and others that the disclosure made herein is presented.

SUMMARY

Technologies are described herein for providing delivery optimization of email messages. In general, the optimization involves providing instant or near instant processing of a message and delivery of the message via email. According to aspects presented herein, a method is provided for instant processing of a message via email. The method includes receiving an instant message to be sent. Additionally, the method sends the instant message via email to multiple recipients. This instant processing of messages allows for Instant Messaging (“IM”) style collaboration over email. Additionally, the features and benefits of email may be used in the IM style collaboration over email.

The message may be delivered to different recipients using different sets of operations depending on one or more conditions. New accounts are not required to implement delivery of an instant message. Any existing user can participate in the communication, and the instant-nature of communication is enabled for any user that meets criteria defined in the system, clients with appropriate client software can also request instant delivery. Techniques providing an acknowledgement of a message delivery may be provided by modifying properties of a mailbox associated with the sender of the message.

It should be appreciated that the above-described subject matter may also be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable medium. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.

DETAILED DESCRIPTION

The following detailed description is directed to technologies for providing delivery optimization of email messages. While the subject matter described herein is presented in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations may be performed in combination with other types of program modules. Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like.

In the following detailed description, references are made to the accompanying drawings that form a part hereof, and which are shown by way of illustration specific configurations or examples. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of a computing system and methodology for providing delivery optimization of email messages will be described.

Email based communications generally involve latency issues, which prevent emails systems from being used for real-time communication applications. The techniques described herein provide the ability for instant communication via email. By use of the techniques disclosed herein, email systems and email accounts may be used for instant communication without having to use specialized applications or accounts configured for specialized applications. As will be described in more detail, the use of a user's existing email account and email application for instant communication allows for increased collaboration between users.

As discussed further below, providing delivery optimization of email messages increases user efficiency by leveraging familiarity with existing applications, such as an email application. User efficiency is also increased by utilizing an existing email account for instant communication, rather than having separate accounts for both email and instant messaging.

Email messages may suffer delays of delivery, which may be a broad range from several seconds to much longer periods of time. Some delays are known to be around ninety seconds. Occasionally, these delays may be even longer. Providing delivery optimization of email messages may provide delivery of messages in less than two seconds. For illustrative purposes, the terms “instant delivery” and “direct delivery” refer to mechanisms associated with reduced latency. By use of the techniques disclosed herein, users do not need an additional application or account to utilize delivery optimization of email messages. The user may utilize an existing email account and email application. Additional details regarding these mechanisms, and others, will be provided below with regard to FIGS. 1-8.

Turning now to FIG. 1, details will be provided regarding an illustrative operating environment and several software components disclosed herein. In particular, FIG. 1 is a system diagram showing aspects of an illustrative system for providing delivery optimization of email messages. The system 100 shown in FIG. 1 includes a client 102 capable of composing, displaying, sending and/or receiving email messages. The client 102 may be one or more computing devices such as the example computing device architecture shown in FIG. 8 and described in more detail below. In this regard, it should be appreciated that the client 102 may refer to any number of computing devices, working alone or in concert, capable of sending and/or receiving email. For example, and without limitation, the technologies utilized herein might include a standalone email application or other applications, such as a web browser and/or services such as those shown in FIG. 7.

FIG. 1 shows the client 102 sending a message 106. The message 106 may be sent to a sender mailbox 104 using one or more known techniques for delivering messages to a mailbox. In some configurations (not shown in FIG. 1), the client 102 transfers the message 106 to the sender mailbox 104. The submission service 110 is then notified of the existence of the new message 106 in the sender mailbox 104. Other configurations for submitting the message 106 are possible. Next, based on one or more factors, the message 106 may be delivered to a recipient mailbox 116 using a direct delivery system 109 or by the use of a processing hub 112.

As will be described in more detail below, depending on one or more aspects of the message 106 and/or other factors, the processing hub 112 may perform operations. For example, and without limitation, the operations may include malware scanning, resolving, compliance checking, queuing, archiving, and/or SPAM filtering, before the message 106 is delivered to the recipient mailbox 116. The processing hub 112 may perform many other complex functions such as creating copies of messages 106 for high availability purposes. Other operations are possible without departing from the scope and spirit of the present description, with the foregoing examples provided only to facilitate this discussion. Depending on the aspects of the message 106 and/or other factors, the system 100 may deliver the message 106 using the direct delivery system 109, which may only perform a subset of operations, e.g., only the malware scanning and compliance checking, before the message 106 is delivered to the recipient mailbox 116. The message 106 may be delivered to some recipients utilizing the direct delivery system 109 and to other recipients from the processing hub 112. The decision to deliver the message 106 utilizing direct delivery system 109 may occur on a per recipient basis. By subjecting the message to a subset of operations using the direct delivery system 109, latency of the delivery to the recipient mailbox 116 may be mitigated. For instance, in some configurations, the delivery of a message 106 using the processing hub 112 may involve a queuing mechanism to manage processing. In some configurations, delivery of the message 106 using the direct delivery system 109 eliminates any queuing as a means to manage processing, and also eliminates some of the processing functions. This elimination benefits in two ways: first it removes the potential for in delays inherent in any queuing function and, second, there are fewer operations required to deliver the message. As described herein, the directed delivery techniques mitigate the need to queue a message, e.g., manage processing, thus tasks such as queuing may be eliminated.

In scenarios where the direct delivery system 109 is used, the message 106 may be written directly into the recipient mailbox 116 by use of a delivery service 114. In doing so, the system 100 may also directly modify the message properties 108 of the message 106 in the sender mailbox 104 indicating acknowledgement of the delivery. In addition, in scenarios where the direct delivery system 109 is used, the processing hub 112 may perform other operations on the message 106, e.g., archiving, search indexing, make a redundant copy for high availability purposes, after the message 106 has been delivered to the recipient mailbox 116.

In some configurations, the system 100 may deliver the message 106 using the direct delivery system 109 or the processing hub 112 depending on the size of the message 106, the number of recipients, a message type, a timestamp indicating an age of the message 106 and/or other factors. Based on one or more conditions considering such factors, the system 100 may also deliver the same message 106 to different recipients using different mechanisms, e.g., the direct delivery system 109 or the processing hub 112. FIG. 2, discussed below, describes the determination of eligibility of messages for the direct delivery system 109.

The submission service 110 may also perform a subset of the processes normally performed in the processing hub 112. If the message 106 is sent to the mailbox of the recipient 116 before being sent to the processing hub 112, then message 106 may be sent additionally to the processing hub 112 for post processing. Although the message may be sent from submission twice, the message 106 may be stopped from being delivered twice to the delivery service 114 of the recipient's mailbox 116. FIGS. 3 and 4, discussed below, cover processing of the message 106 prior to delivery and post processing of the message 106 after it has already been sent once to the delivery service 114 of the recipient's mailbox 116.

As summarized above, the message properties 108 may also be utilized to track delivery, non-delivery and other characteristics of the message 106 on a per recipient basis. For example, some message properties 108 may indicate if a message is read or unread. As will be described herein, these properties are updated directly by the system 100 for instant acknowledgement of delivery and/or other functions or tasks. FIG. 5, discussed below, covers acknowledgement of messages utilizing message properties 108.

Referring now to FIG. 2, additional details regarding the technologies for providing delivery optimization of email messages are described. In particular, FIG. 2 is a flow diagram showing an illustrative routine 200 that illustrates aspects of the above-described processing of the system illustrated in FIG. 1.

It should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states operations, structural devices, acts, or modules. These operations, structural devices, acts and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. It should also be appreciated that more or fewer operations may be performed than shown in the figures and described herein. These operations may also be performed in a different order than those described herein.

The routine 200 begins at operation 202, where the submission service 110 receives the message 106 from the client 102. The submission service 110 may receive the message 106 in response to the client 102 sending the message 106 to the sender mailbox 104.

From operation 202, the routine 200 proceeds to operation 204, where the submission service 110 may determine whether the message 106 qualifies to be delivered via direct delivery system 109. The submission service 110 may utilize factors to determine whether the message 106 qualifies for direct delivery system 109. These factors might include, but are not limited to, message size, message type, the number of recipients, recipients belonging to a same organization as the sender, the type of recipient and/or a timestamp of the message 106. Any number of these or other factors may be utilized to determine whether the message 106 qualifies to be sent on the direct delivery route to the mailbox of the recipient 116.

The message size of the message 106 may be utilized to determine eligibility of the message 106 for transmission using the direct delivery system 109. For example, a message size above a certain threshold may not be sent on this path and may instead be sent to the processing hub 112.

Additionally, the type of the message 106 may be utilized to determine eligibility of the message 106 for transmission using the direct delivery system 109. For example, meeting notifications may be sent to the processing hub 112 instead of using the direct delivery system 109.

The number of recipients of the message 106 may also be used to determine eligibility of the message 106 for transmission using the direct delivery system 109. As an example, if the number of recipients exceeds a threshold, the message 106 may be sent to the processing hub 112 for delivery of the message 106 to the recipients.

The submission service 110 may also determine eligibility of the message 106 for transmission on the direct delivery system 109 depending on one or more associations between the sender and the recipients. For example, if the sender is in the same organization as the recipients, e.g., same set of domains managed by a single organization/entity, the message 106 may be eligible for transmission using the direct delivery system 109. For recipients that are external to the sender, e.g., a different organization, the message 106 may be sent using the processing hub 112. Additionally, a message 106 may be sent to a subset of recipients using the direct delivery system 109 if the subset of recipients are in the same organization, and also deliver the same message 106 to other recipients outside the organization using the processing hub 112. For illustrative purposes, in a multi-tenant system if a message is sent from one organization to another organization, the message is crossing from a first mailbox associated with one tenant to a second mailbox another tenant of the system.

Also, the type of recipient may determine whether the message 106 is sent via direct delivery system 109 to the recipient 116 for these recipients. As an example, recipients that are on a distribution list may only receive messages 106 via the processing hub 112.

In another example, a single organization may have a number of users in a first system, e.g. a cloud system, and number of users in a second system, e.g., an on-premise system. In such a structure, a message 106 may only be eligible for using direct delivery system between users within one of the systems. For instance, a user of the cloud system may only use direct delivery system for other users on the cloud system. In this example, if a user of the cloud system sends a message 106 to a user of the on-premise system, the message may not be eligible for using direct delivery system, and other delivery mechanisms may be used.

As another example, a message 106 may be sent from a sender to multiple recipients, where the recipients and the sender are in a single organization. In this example, some of the recipients have mailboxes in the cloud, while other recipients have mailboxes on-premise. If the sender's mailbox 104 is also in the cloud, the message 106 will be delivered to the recipients with mailboxes in the cloud using the direct delivery system 109, while also delivering the same message 106 to the other recipients with mailboxes in the on-premise system using the processing hub 112.

Additionally, a timestamp of the message 106 may determine whether the message 106 is sent directly to the mailbox of the recipient 116 for these recipients. As an example, if a timestamp indicates that the message 106 is older than a certain threshold, then the message may be sent to the processing hub 112 prior to delivery, since the timestamp may indicate that the message 106 is no longer current enough for instant communication. For illustrative purposes, factors and/or conditions using the timestamp is referred to as a “freshness” factor.

Along with determining whether the message 106 qualifies for direct delivery system 109, the submission service 110 may perform a subset of the processing that normally occurs in the processing hub 112. The processing occurring in direct delivery system 109 might include, but is not limited to, malware scanning and compliance checking. These delivery tasks may also be used to determine eligibility of the message 106 for transmission using the direct delivery system 109. Thus, in addition to checking the conditions described above, e.g., the number of recipients, a subset of the delivery operations may be executed as part of operation 204. This may include tasks such as malware scanning, resolving, and compliance. As these tasks are executed the system may determine that the message 106 is not eligible for direct delivery system 109. For instance, this may occur if one or more of the eligibility criteria are not met. In some configurations, if these tasks are performed successfully, the routine 200 proceeds to operation 208 where a delivery attempt is made. In another example, certain conditions related to a message 106 may be used to determine if the message 106 is eligible for transmission using the direct delivery system 109. For instance, the system 100 may be configured to examine messages 106 during submission to determine if the messages require a particular task. If it is determined that a message 106 requires a particular task during submission, such as queuing, the system 100 may determine that the message 106 is not eligible for transmission using the direct delivery system 109. In such an example, a system may disqualify a message 106 for direct delivery system if the message 106 requires queuing since queuing may involve multiple operations to obtain information from external resources, which may add inherent latency. This example is provided for illustrative purposes and is not to be construed as limiting, as tasks other than queuing and/or other conditions associated with individual messages may be used to determine if a message is eligible for directly delivery 109.

From operation 204, the routine 200 may proceed to operation 206 if it is determined that the message 106 does not qualify for direct delivery system 109. At operation 206, the message 106 is subject to a set of number of email processing operations. As discussed above, the processing hub 112 may perform number of tasks on the message 106, which may involve a resolving process, malware scanning, compliance checking and other tasks. After the processing hub 112 completes its tasks, the message 106 may be delivered to the mailbox of the recipient 116. If one or more delivery tasks were performed as part of operation 204, operation 206 may skip those previously executed tasks. For instance, if operation 204 performed the malware scanning, operation 206 may skip that task. From operation 206, the routine 200 may continue to operation 214 where routine 200 ends.

From operation 204, the routine 200 may proceed to operation 208 if it is determined that the message 106 qualifies for direct delivery system 109. At operation 208, an attempt is made to deliver the message 106. In some configurations, operation 208 may involve a direct write of the message 106 into the recipient mailbox 116. The delivery attempt may be made using any known technique. In addition, the verification of the delivery may involve one or more known technologies. For example the delivery attempt may include one or more technologies such as those using Hypertext Transfer Protocol (HTTP). If the delivery of the message 106 is unsuccessful, then routine 200 continues to operation 206. Although this example utilizes HTTP, it can be appreciated that this example is provided for illustrative purposes and is not to be construed as limiting as many other transfer protocols may be used with the routine 200 such as a Simple Mail Transfer Protocol (SMTP), an Internet Message Access Protocol (IMAP), a Post Office Protocol (POP) and a Messaging Application Programming Interface (MAPI). At operation 206, the message 106 may go through hub processing 112, as discussed above. The message 106 may then be delivered via other techniques, such as those utilizing Simple Mail Transfer Protocol (SMTP). From operation 206, the routine 200 may continue to operation 214 where routine 200 ends.

From operation 208, the routine 200 proceeds to operation 210 when the delivery attempt is successful. At operation 210 the system 100 may generate an acknowledgement. In one example, the sender may receive an instant acknowledgment that the message 106 was successfully delivered to the recipient(s). This operation may involve a direct write into the properties 108 of the message 106 in the sender mailbox 104. Utilizing the message properties 108, message delivery can be tracked on a per recipient basis. Rather than receiving a delivery receipt, the message properties 108 may be altered to indicate delivery for a particular recipient. FIG. 5, discussed below, covers acknowledgement of messages utilizing message properties 108.

From operation 210, the routine 200 continues to operation 212 where the message 106 may undergo additional processing. As discussed above, a message 106 that is delivered using direct delivery system, may only be subjected to a subset of tasks that would occur if the message 106 is delivered using the hub 112. This message would then be subject to post processing of operation 212 which may include archiving, or making a copy for redundancy of one or more messages or other complex operations. From operation 212, the routine 200 proceeds to operation 214, where the routine 200 ends.

Referring now to FIG. 3, which is a system diagram showing aspects of an illustrative system disclosed herein for providing delivery optimization of email messages. The system 300 shown in FIG. 3 includes the client 102 and the sender mailbox 104. Additionally, the delivery service 114 and the recipient mailbox 116 are included in FIG. 3.

FIG. 3 illustrates the direct delivery system that messages may follow. As discussed above, the submission service 110 may perform a subset of operations that are performed by the processing hub 112. Once the message 106 is delivered via direct delivery system, the message 106 may undergo processing that is normally managed by the processing hub 112.

The post processing 304 may process tasks that were initially skipped by the submission service 110. These tasks may involve one or more tasks including archiving, or making a copy for redundancy, among other tasks. Once the post processing 304 is completed, the message 106 is not delivered again to the recipient mailbox 116. FIG. 4, discussed below, covers the processing and post processing of the message 106 in more detail.

Turning now to FIG. 4, additional details will be provided regarding the technologies presented herein for providing delivery optimization of email messages. In particular, FIG. 4 is a flow diagram showing an illustrative routine 400 that illustrates aspects of the post processing illustrated in FIG. 1 and FIG. 3.

The routine 400 begins at operation 402, where a message is sent by an end user. The end user may send the message using an application utilizing a computer, such as the client 102. From operation 402 the routine 400 continues to operation 404.

At operation 404, the message may be stamped with a direct delivery tag. The direct delivery tag may indicate that the client or another device has made a determination to use direct delivery system to send the message. Alternatively, the message may be stamped with a direct delivery tag may indicate that the message has been certified to send via direct delivery system. The certification process may include routine 200 discussed above regarding FIG. 2.

From operation 404 the routine 400 may continue at operation 406. At operation 406, the message may be sent via direct delivery system. As summarized above, some tasks may be performed by the processing hub 112 may be skipped by sending the message via direct delivery system. In some configurations, direct delivery system may still process one or more tasks, such as malware scanning, resolving, compliance processing. Operation 406 may involve a direct write into the recipient mailbox. From operation 406, the routine 400 continues to operation 408.

At operation 408, the message may be processed to subject the message to tasks that were not performed using the direct delivery system. For example, this processing may include archiving, making redundant copies, and other tasks normally managed by the processing hub 112. From operation 408, the routine 400 proceeds to operation 410, where the routine 400 ends.

Referring now to FIG. 5, additional details will be provided regarding the technologies presented herein for providing delivery optimization of email messages. In particular, FIG. 5 is a flow diagram showing an illustrative routine 500 that provides instant acknowledgement.

The routine 500 begins at operation 502, where the message 106 may be sent via direct delivery system. Operation 502 may involve a direct write into the recipient mailbox and operation 502 may only involve a subset of tasks performed by the processing hub 112. From operation 502, the routine 500 continues on to operation 504. At operation 504, the sender receives instant acknowledgment of delivery receipt of the sent message. The sender may receive the acknowledgment via a direct altering of the message properties 108 in the sender mailbox 104. As discussed above, the message properties 108 may be altered on a per recipient basis. The altering of the message properties 108 may replace the use of a delivery receipt that is communicated from a recipient mailbox.

From operation 504, the routine 500 may continue on to operation 506. At operation 506, the message 106 may be accessed from the recipient mailbox 116, e.g., a recipient user may read the message 106. From operation 506 the routine 500 may continue to operation 508. At operation 508, the sender receives instant acknowledgment of the message 106 being read by the recipient. As in operation 504, the sender may receive the acknowledgment via altering the message properties 108. As discussed above, the message properties 108 may be altered on a per recipient basis. The altering of the message properties 108 may replace the use of a read receipt.

In some configurations, a read receipt may be sent to the mailbox of the sender 104. Instead of delivering the read receipt to a user's mailbox as a new message, the system utilizes the data of the read receipt to change the message properties 108 of the original message 106 in the sender's mailbox. Based on the altered message properties 108, a client may change the appearance of the sent message 106 to graphically indicate the acknowledgement.

Additionally, the message properties 108 may be altered to indicate other statuses of the message 106. The statuses may indicate not delivered and/or not read. A message that is deleted prior to being read can generate a status of not read. The message properties 108 can be altered on a per recipient basis to indicate this status. Likewise, if a message has not been successfully delivered, the message properties 108 can be altered on a per recipient basis to indicate this result. From operation 508, the routine 500 proceeds to operation 510, where the routine 500 ends.

FIG. 6 illustrates a computer architecture 600 for a device capable of executing some or all of the software components described herein for providing delivery optimization of email messages. Thus, the computer architecture 600 illustrated in FIG. 6 illustrates an architecture for a server computer, mobile phone, a PDA, a smart phone, a desktop computer, a netbook computer, a tablet computer, and/or a laptop computer. The computer architecture 600 may be utilized to execute any aspects of the software components presented herein.

The computer architecture 600 illustrated in FIG. 6 includes a central processing unit 602 (“CPU”), a system memory 604, including a random access memory 606 (“RAM”) and a read-only memory (“ROM”) 608, and a system bus 610 that couples the memory 604 to the CPU 602. A basic input/output system containing the basic routines that help to transfer information between elements within the computer architecture 600, such as during startup, is stored in the ROM 608. The computer architecture 600 further includes a mass storage device 612 for storing an operating system 618 and one or more application programs including, but not limited to, a web browser program 624, and an email application 622. Other executable software components and data might also be stored in the mass storage device 612.

The mass storage device 612 is connected to the CPU 602 through a mass storage controller (not shown) connected to the bus 610. The mass storage device 612 and its associated computer-readable media provide non-volatile storage for the computer architecture 600. Although the description of computer-readable media contained herein refers to a mass storage device, such as a hard disk or CD-ROM drive, it should be appreciated by those skilled in the art that computer-readable media can be any available computer storage media or communication media that can be accessed by the computer architecture 600.

Communication media includes computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics changed or set in a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer-readable media.

By way of example, and not limitation, computer storage media may include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. For example, computer media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other solid state memory technology, CD-ROM, digital versatile disks (“DVD”), HD-DVD, BLU-RAY, or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and which can be accessed by the computer architecture 600. For purposes of the claims, the phrase “computer storage medium,” and variations thereof, does not include waves or signals per se and/or communication media.

According to various configurations, the computer architecture 600 may operate in a networked environment using logical connections to remote computers through a network such as the network 620. The computer architecture 600 may connect to the network 620 through a network interface unit 614 connected to the bus 610.
